STACKING-DERRICK.

Q?EQIEIGATEON forming part of Letters Patent No. 350,824, dated October 12, 1886.

Application tiled June 1,1886. Serial No. 203,789. (No model.)

To all whom, it may concern: Y Be it known that I, Annan GALLAGHER, a citizen of the United States, and a resident of Mode, in the county of Shelby and State of Illinois, have invented certain new and useful Improvements in Stacking-Derricks; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying dran'- ing, which forms a part of this specification, and in which my improved derrick is represented by a perspective vien".

My invention has relation to stacking derricks; and it consists in the improved construction and combination of parts, as will be hereinafter fully described, and pointed out in the claims.

In the accompanying drawing letters are used to indicate the several parts, A representing the run ners ofthe sled; B, the benches, C, the Xshaped trusses, the front upper prongs of which are longer than the rear ones; D, braces from the front part of the trusses to the front ruimer of the sled, E, stays from the back part of the trusses to said runner, F, top rails, one extending in an inclined manner across the upper end of each truss and p'rojeeting from the front thereof, the middle rail projecting the farthest; G, braces from said rails to said trusses; I-I, atie-beam at the back ends of said rails, I, a beam connected to the A under sides ol' the front ends of said rails,

which, while it acts as a tie-beam, also forms y a runway for a hay-elevator, or serves as a means for attachment of such runway, J, a yard hinged to the middle top rail, to be used as a runway or serve as a means for attaclr ment of one; K, links for supporting the outer Yend and middle of said yard 5 L, guys attached to the rear upper corners ot' the derrick; M, a rope for running the elevator when a stack is to be formed, and N one for running the elevator when a rick is to be formed.

The runners are provided at each end with meansfor hitching a team to them for the purpose of hauling the derrick from place to place.

When a stack is to be termed, the elevator is attached to the yard while in the position represented in full lines, the rope lll passing from the elevator, which is lowered from the outer end ol' the yard, back over the derrick,V

down through a pulley, O, secured to the ground, and then to the horse or other means used for running said elevator.

\Vhen the derriek is to be used in forming a rick, the links are detached from the yard and the latter swung down and secured to the truss, out ot' the way of the elevator. (See dotted position of said yard Then the rope N is passed from the elevator, which is lowered from one endgof the l'rout tie-beam, along under saidbeam to its opposite end, there through directioirehanging pulleys back over the derriek, do\vn through a pulley, l), secured to the ground, and then tothe means employed in running the elevator.

lf it is desired to use the derrick wholly for stacking, the end trusses with their braces and stays and the tie-beams may be dispensed with. On the other hand, if the dci-rick is to lbe used exclusively for building ricks, the yard and its links may be dispensed with and the middie rail made no longer than the end ones, or the end ones may be made as long as the mitldle one, and the projecting end of eaeh provided with an eyebolt or a hook, (see dotted lines,) to which a pulley may he attached,and'

the simple horse-fork and rope used on iirst oneI rail, then another, till the rick is finished.

3y passing the hoistingropes-back over the derrick to pulleys secured to the ground, the necessity ot' staking the derriek-to the ground is obviated, since by such arrangement the weight of the load on the elevator is borne equally by the opposite sides of the derrick. The guys shown are merely to keep the apparatus from blowing over when not in use.

A stacking or rickiug derrick constructed as herein described is light, strong, durable, and easily moved about. This last feature is a most important one, since through it much time is saved which has heretofore been spent in handling derricks that must be taken to pieces every time they are moved.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United Statesw IOO 1. In a stacliing-derrck, the combination of a sled, X-shaped trusses having one upper prong ofv each longer than the other, braces and stays from said trusses to 'said sled, top rails, braces from said rails to said trusses, a tie-beam across one end of said rails and adapted to act as or form a means of attachment for a runway, and means for operating an elevator upon said runway.

2. In a stacking-derrick, the combination of a sled, X-sl1aped trusses, braces and stays, inclined top rails, the middle one of which is longer than the others, a yard hinged and linked to said rail and adapted to act as or form a means oi' attachment for a runway,and means for operating an elevator upon said runway.

3. In a staekingderriek, the combination of a sled, an X-shaped truss, braces and stays from said truss to said sled, an inclined topy rail, a yard secured in n horizontal position to said rail and adapted to act as a runway, and

my own I have hereunto afiixed my signature A in presence of two witnesses.

ABRAM GALLAG HER.
